Fizzy Fish

Chewy sweets made exclusively for Marks and Spencers, which (sadly) probably limits them to the UK. However, given their properties, I wouldn't be surprised if they turned out to be a banned export.

They're lemon flavoured gummy things .. coated with a 'fizzy' layer of sparkly dust. They are wonderfully sour .. but be warned eating a whole packet will result in a Lisa Simpson style "I can see through time!" moment. The roof of your mouth will collapse, and you will lose all control of your jaw.
